Tomato Yield Effects of Reciprocal Hybridization of Solanum lycopersicum Cultivars M82 and Micro-Tom
Sujeevan Rajendran, Jong Hyang Bae, Min Woo Park, Jae Hyun Oh, Hwang Weon Jeong, Young Koung Lee, Soon Ju Park
Plant Breed. Biotech. 2022;10(1):37-48.   Published online March 28, 2022

Plant breeders have accumulated hybrid effects to increase food production in order to counteract the loss of arable land. Hybrids may possess novel genetic potential to increase agricultural productivity; however, the relationships between genetic resources for optimizing crop productivity remain mostly unclear. In this study, we recorded heterosis effects of genetically inherited traits by reciprocal hybridization of the Solanum lycopersicum cultivar Micro-Tom and the commercial cultivar M82, which are currently available as in silico mutant populations, to identify mutant genes which can induce heterosis. The genetic variations between M82 and Micro-Tom caused intermediate phenotypic effects with regard to flowering time, plant height, and fruit size, indicating additive interactions among variations with a hybrid background. The total yield of F1 hybrid was similar to that of cultivar M82, regardless of reduced vegetative biomass, and it revealed an overdominance effect regarding number of harvested fruits. The inheritance of the phenotypes was similar among reciprocal F1 hybrids with different paternal and maternal materials. Based on the consistency of hybrids and wild types, Micro-Tom mutants showing floral homeotic defects and large plant size can be efficiently screened for overdominant yield mutants in F1 hybrids. Therefore, we suggest that identical traits in reciprocal hybrids between Micro-Tom and M82 varieties are useful as control F1 hybrids to improve field tomato productivity by screening mutant hybrids of Micro-Tom mutants and commercial variety M82.

Visiting Bitter Gourd (Momordica charantia) from a Breeding Perspective: A Review
Hari Kesh, Prashant Kaushik
Plant Breed. Biotech. 2020;8(3):211-225.   Published online September 1, 2020

Bitter gourd is an important vegetable of the family Cucurbitaceae, cultivated mainly in humid and subtropical Asia. Bitter gourd is a vegetable with immense health benefits due to the presence of medicinal compounds such as charantin, vicine, and polypeptide-p, which play essential roles in lessening blood glucose levels. Moreover, bitter gourd fruits are particularly rich in vitamin C, minerals, and carotenes. Here, an effort has been made to critically evaluate the extent of achievements during the enhancement and enactment of bitter gourd breeding programs with the use of latest technologies. Broadening the genetic base of cultivated bitter gourd varieties as a result of enrichment of existing resources by using wild species in breeding programs. Practical seed production technological know-how along with the use of the MS system (male sterility)/chemical-induced sterility procedure is nonetheless vital to cope with market demands. Superior yielding bitter gourd hybrids combining early maturity and resistance to biotic and abiotic stresses are regularly needed to cope with the challenge of bitter gourd production.

Identification of Heterosis QTLs for Yield and Yield-Related Traits in Indica-Japonica Recombinant Inbred Lines of Rice (Oryza sativa L.)
Chang-Kug Kim, Sang-Ho Chu, Han Yong Park, Jeonghwan Seo, Backki Kim, Gileung Lee, Hee-Jong Koh, Joong Hyoun Chin
Plant Breed. Biotech. 2017;5(4):371-389.   Published online December 1, 2017

Supplying sufficient rice to growing populations is a global challenge. Hybrid indica rice varieties exploiting heterosis have increased yields, but inter-subspecific crosses between indica and japonica varieties are hampered by sterility. Examination and genetic understanding of yield heterosis in indica/japonica crosses addressing yield barriers are basic requirements. In this study, QTLs for heterosis of yield traits were identified in indica-japonica recombinant inbred lines (RILs) using a total of 178 RILs originating from Dasanbyeo (indica) × TR22183 (japonica) (DT-RILs) and their backcrossed populations. Nine of sixty-six major quantitative trait loci (QTLs) identified in DT-RILs exhibited heterosis. Heterosis QTLs clustered with other traits on chromosomes 1, 4, and 8, and clusters were conserved between different RILs. The clusters contained several known yield enhancement genes/QTLs. Specific heterotic allele combinations contributed to four major heterosis QTLs, particularly for panicle and spikelet number traits. Heterosis for yield and yield-related traits was explained by the harmonized effects of overdominance, dominance, and epistatic interactions in inter-subspecific breeding populations.
